PURPOSE:To make it possible to set timer-based operation accurately and simply, by making 24h setting at the same when a reduction time counter section indicates zero and counting the time repeatedly until a timer setting section changes setting time disregarding ON/OFF status of an operation switch and a timer setting section. CONSTITUTION:A combustion device is provided with a time setting section 7 which starts combustion in a predetermined time, a timer adjusting section 8 which sets the time elapsed from the start of combustion and a reduction time counter section 9 which counts time reduced from the predetermined time, judges the time at a comparison section 10 when the value is turned to a specified value and outputs signals to the time setting section 7. This reduction time counter section 9 counts time reduced from a predetermined time disregarding the ON/OFF status of an operation switch 6 and the time setting section 7 and makes 24h setting again when the preset time is reduced to zero, thus repeatedly counting down. |
